The transmission mechanism provided by the invention has advantages of steadiness in operation, low noise, capability of repeating transmission and the like.
Description
Technical field
The present invention relates to the transmission device field, be specifically related to a kind of compound drive mechanism that returns.
Background technique
Transmission is meant and utilizes member or mechanism that power is delivered to another part from the part of machine that transferring power makes machine or machine part motion or running.The device of transferring power and motion also can be used to distribute energy, changes rotating speed and forms of motion.The working portion that machine is normally given machine by it with the power and the transmission of movement of power engine generation.Transmission is divided into mechanical transmission, fluid transmission and electric drive 3 big classes.
Mechanical transmission is used very extensive in mechanical engineering, mainly is meant the transmission that utilizes machinery type transferring power and motion.Be divided into two classes: the one, by frictional force transferring power and the friction driving between parts, the 2nd, mesh or mesh the engagement driving of transferring power or motion by driving link and driven member by middleware.Wherein friction driving realizes stepless change easily; can both adapt to the bigger transmission occasion of distance between shafts greatly; overload is skidded and can also be played the effect of buffering and protection transmission device, but this transmission generally can not be used for powerful occasion, can not guarantee velocity ratio accurately.Lean on the engagement of driving link and driven member or mesh the engagement driving of transferring power or motion, comprise gear transmission, chain-driven, power screw and harmonic driving etc. by middleware.Engagement driving can be used in powerful occasion, and velocity ratio is accurate, but higher accuracy of manufacturing and the installation precision of fitness for purpose.It is poor that but gear transmission, chain-driven also have transmission stability, can produce shortcomings such as additional dynamic load, vibration, impact and noise during running, and can't return compound transmission.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of operating steadily, noise is low and can return the driving mechanism of compound transmission.
For achieving the above object, technological scheme proposed by the invention is: a kind ofly return compound driving mechanism, it is characterized in that, comprise: power plant, rocker bar bearing, pulley detent mechanism, fixed guide, described power plant are fixed on the rocker bar bearing, and drawing ear to link to each other in the power plant piston with the ear that draws of pulley detent mechanism by pull bar, described pulley detent mechanism is installed on the fixed guide.
Further, described pulley detent mechanism comprises: a pulley pawl assembly support, pulley pawl assembly support end contains to draw on ear, the pulley pawl assembly support pulley rotating shaft is installed, in the pulley rotating shaft pulley is installed, on the pulley pawl assembly support ratchet rotating shaft is installed, in the ratchet rotating shaft ratchet is installed, the ratchet return spring is installed on the ratchet.
Further, described power plant can be the feed screw nut line handspike of fluid power cylinder, Pneumatic pressure power cylinder or driven by motor.
Further, described fixed guide can be linear, circular arc or other curves; Fixed guide is provided with single guide according to demand, also can be two-sided guide rail.
Further, described pulley rotating shaft can be provided with 1 or 2 according to load, and every pulley rotating shaft can be provided with 1 pulley 2 pulleys also can be set.
Further, thereby described ratchet can arrange according to demand that the ratchet direction realizes unidirectional straight line or curve transmission, and ratchet also can be with the hinge or the replacement ratchet that is fixedly connected, and then realizes returning compound straight line or curve transmission.
In sum, of the present inventionly return compound driving mechanism, by power plant energy is passed to the pulley detent mechanism through pull bar, ratchet on the pulley detent mechanism passes to kinetic energy and needs by the object of transmission such as turntable etc., fixed guide can be arranged to line, circular arc or other curves, the pulley detent mechanism returns reciprocating motion on fixed guide, and then realizes by the compound transmission of returning of transmission object.This structure has advantages such as simple in structure, that transmission is effective, operate steadily.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Shown in Fig. 1 basic block diagram of the present invention, a kind ofly return compound driving mechanism, comprise power plant 1, rocker bar bearing 2, pulley detent mechanism 3, ratchet 301, fixed guide 4 and pull bar 5, power plant 1 are fixed on the rocker bar bearing 2, and drawing ear to link to each other in the piston of power plant with the ear 306 that draws of pulley detent mechanism 3 by pull bar 5, pulley detent mechanism 3 is installed on the trapped orbit 5.Power plant 1 provide kinetic energy, return reciprocating motion by pull bar 5 pulling pulley detent mechanisms 3 on fixed guide 4, and then need or do and return reciprocating motion by the object of which movement of transmission by ratchet 301 pullings of pulley detent mechanism 3.
Further, as shown in Figure 2, pulley detent mechanism 3 comprises ratchet 301, pulley pawl assembly support 302, pulley 303, pulley rotating shaft 304, ratchet rotating shaft 305, draws ear 306, ratchet return spring 307, draw ear 306 to be positioned at pulley pawl assembly support 302 ends, and draw ear to link to each other with power plant 1 piston by pull bar 5.Pulley rotating shaft 304 is installed on the pulley pawl assembly support 301, and pulley 303 is installed in the pulley rotating shaft 304, and pulley 303 is installed on the fixed guide 5, and returns reciprocating motion on fixed guide 5.This figure middle pulley rotating shaft 304 has two, lays respectively at pulley pawl assembly support 302 front and back, and every pulley rotating shaft 304 has two pulleys 303, lays respectively at pulley pawl assembly support 302 left and right sides.Ratchet 301 is installed in the ratchet rotating shaft 305, and ratchet rotating shaft 305 is installed on the pulley pawl assembly support 302, and ratchet return spring 307 is installed on the ratchet 301.When power plant 1 pulling pulley detent mechanism 3 is done on fixed guide 5 when returning reciprocating motion, ratchet 301 pullings need to be rotated by the object of transmission, and during the transmission certain distance, ratchet return spring 307 is stretched to a certain degree, and then drive ratchet 301 and reset, realize returning composite motion.
